Abstract
Energy utilization of agricultural waste, due to the depletion of petroleum resources and the continuous deterioration of the ecological environment, has become an increasingly important development area at present, with broad prospects. The Citespace software was used to systematically summarize the research hotspots, development, and frontiers of researches on the energy utilization of agricultural waste in China from 1999 to 2018. The results show that (1) the number of publications in this field has increased, which includes a steady development stage, a rapid development stage, and a fluctuation and decline stage. (2) Research hotspots focused on technology for energy utilization of agricultural waste, benefits analysis of energy utilization of agricultural waste, energy conversion and upgrading path of agricultural waste, and energy potential of agricultural waste. (3) Development of research hotspots go through five stages: “technology for energy utilization of straw and the disposal of livestock and poultry waste”, “exploration of energy utilization mode of agricultural waste and the disposal of by-product from energy utilization of agricultural waste”, “technology upgrading from agricultural waste to fuel ethanol and recycling of livestock and poultry waste”, “resource recycling of by-product from biogas ” and “energy utilization of livestock and slaughterhouse waste”. It has revealed the focus in this field was changing from planting waste to breeding waste, and from unprocessed waste to by-product from energy utilization. (4) Energy utilization of slaughterhouse waste and cow manure has started to be considered as the frontiers of researches.
Highlights
Energy utilization of agricultural waste is among the most effective methods for disposing of agricultural waste [1]
Based on the attention and influence of the research hotspot, combined with the horizontal and vertical aggregation of keywords, by dynamic analysis, the development of research hotspots of energy utilization of agricultural waste go through five stages: “technology for energy utilization of straw and the disposal of livestock and poultry waste”, “exploration of energy utilization mode of agricultural waste and the disposal of by-product from energy utilization of agricultural waste”, “technology upgrading from agricultural waste to fuel ethanol and recycling of livestock and poultry waste”, “resource recycling of by-product from biogas ”, “energy utilization of livestock and slaughterhouse waste”
The development of research hotspots of energy utilization of agricultural waste go through five stages: “technology for energy utilization of straw and the disposal of livestock and poultry waste(1999–2002),” “exploration of energy utilization mode of agricultural waste and the disposal of by-product from energy utilization of agricultural waste(2003-2006)”, “technology upgrading from agricultural waste to fuel ethanol and recycling of livestock and poultry waste(2007-2010),” “resource recycling of by-product from biogas (2011-2014),” “energy utilization of livestock and slaughterhouse waste(after 2015).”
Summary
Energy utilization of agricultural waste is among the most effective methods for disposing of agricultural waste [1]. It refers to the conversion of agricultural waste into clean energy. This includes the use of crop field residues such as crop straw, crop process residues such as rice husk and corncob, livestock breeding waste such as farm bedding and manure, and slaughterhouse waste such as carcasses and wastewater. A great variety of by-products are generated during the process of energy utilization of agricultural waste, such as biogas residue. With the deepening of research on energy utilization of agricultural waste, scholars started to devote themselves in the study of biogas residue disposal, in order to prevent secondary pollution [4,5]
